From the Department of Natural Resources: Report forest fires at 800-562-6010.
Thunderstorms bearing lightning strikes detected 40 miles off the coast of Grays Harbor at 10 a.m. today are expected to roll on to the coast by noon and Clallam and Jefferson counties by this afternoon, the National Weather Service said this morning.
“The greatest threat of lightning is this afternoon,” fire weather forecaster Andy Haner said.
A red flag alert, which indicates extreme fire danger due to lack of rain, will continue in effect for the western side of the North Olympic Peninsula from Lake Crescent west through 11 p.m. today and the eastern side of the North Olympic Peninsula from Lake Crescent through Port Townsend until 5 a.m. Sunday, Haner said.
“I’m pretty sure by the time the expiration times come around, the lightning threat will have ended,” he said.
The thunderstorms are expected to produce less than the quarter-inch of rain that is normally needed to pierce a forest canopy and dampen the tinder-dry forest floor, Haner said.
It’s been about a month since it’s rained a quarter inch in Clallam and Jefferson counties, Haner said.
